The modern theory of biological evolution: an expanded synthesis

U Kutschera, KJ Niklas - Naturwissenschaften, 2004 - Springer

proposed natural selection as the basic mechanism responsible for the origin of new …

Antibiotic tolerance facilitates the evolution of resistance

I Levin-Reisman, I Ronin, O Gefen, I Braniss… - Science, 2017 - science.org
Controlled experimental evolution during antibiotic treatment can help to explain the

Beneficial mutation–selection balance and the effect of linkage on positive selection

MM Desai, DS Fisher - Genetics, 2007 - academic.oup.com
When beneficial mutations are rare, they accumulate by a series of selective sweeps. But
when they are common, many beneficial mutations will occur before any can fix, so there will …

On the accumulation of deleterious mutations during range expansions

S Peischl, I Dupanloup, M Kirkpatrick… - Molecular …, 2013 - Wiley Online Library
We investigate the effect of spatial range expansions on the evolution of fitness when
beneficial and deleterious mutations cosegregate. We perform individual‐based simulations …

The speed of evolution and maintenance of variation in asexual populations

MM Desai, DS Fisher, AW Murray - Current biology, 2007 - cell.com
Background The rate at which beneficial mutations accumulate determines how fast asexual
populations evolve, but this is only partially understood. Some recent clonal-interference …
